ubuntu 18.04 安装pytorch

前面安装了 cuda ,cudann 现在终于可以安装 pytorch 了

官网下载

https://pytorch.org/
执行上面的语句 发现有问题

单独下载 cuda tookit

https://repo.anaconda.com/pkgs/main/linux-64/cudatoolkit-10.1.243-h6bb024c_0.conda

然后本地安装
进入文件所在的目录

conda install --use-local      ./cudatoolkit-10.1.243-h6bb024c_0.conda

下面这几个也很难下载：
https://repo.anaconda.com/pkgs/main/linux-64/python-3.7.7-hcf32534_0_cpython.conda
https://repo.anaconda.com/pkgs/main/linux-64/pandas-1.0.3-py37h0573a6f_0.conda

conda下载慢问题

更改下载源

sudo  gedit  ~/.condarc

填入
